Arm Knitting Scarf. This takes so little time that if you had the yarn on hand you could make a scarf before you had to go somewhere! Go on youtube and search: DIY arm knitting- 30 minute infinity scarf.
Take an old sweater. Cut a slit in along the shoulder down about 7". Fold over raw edge and sew in place. Sew a piece of ribbon about 15" long to one side of neckline and another ribbon to the other side of the neckline. Tie together!
scarf: get a bunch of yarn, cut into strands at desired length. holding all strands together, sew back and forth at desired intervals with whatever color(s) of thread you have near your sewing machine.
My dad showed me how to do this & I wear mine with my wedding band. It's cool, because the wording on the edge of the coin ends up in the middle of the ring! Do you have a quarter from 1964 or before? If you do, it is made of silver. You can turn that coin into a nice silver band using a spoon, a drill, and a metal file. (And no, it's not illegal.)
